Abstract
An apparatus and method for slitting an endless strip of material having substantially planar surfaces by forming a pair of adjacent grooves in each surface of the material with corresponding grooves in each surface of the material being orthogonally aligned and applying a force normal to the planar surfaces of the material and between adjacent grooves and of sufficient magnitude to shear the material along a line connecting corresponding grooves. For this purpose a pair of scoring knives for each slit are mounted in relative orthogonal alignment with respect to the planar surfaces of the material with one on each side of the material. The knives form the adjacent grooves in each surface of the material.
